The following is a list of kits and components that may be purchased. Major components shown below are supplied on an exchange basis. Your exchange components should be in re-buildable condition to be accepted as a core. We can supply a copy of the core policy upon request. We welcome you sending in any core items for exchange ahead of time. That way they can be pre- inspected as an acceptable or unacceptable core. TAD will pay a one-time freight charge for your core parts being returned from within the 48 continental states. All items should be returned on the skid that was shipped to you, where applicable.
